3GhKT2: a novel K^+ transporter gene in cotton(Gossypium hirsutum)显示文摘Potassium is an essential nutrient for plant growth and productivity of crops. K+transporters are important for K+uptake and transport in plants. However,information on the function of K+transporters and K+channels in cotton is limited. The KT/KUP/HAK protein family is essential for a variety of physiological processes in plants, including nutrient acquisition and regulation of development. This study, identified a K+transporter gene,Gh KT2, expressed in the roots of cotton(Gossypium hirsutum) cv. Liaomian17. The deduced transcript of Gh KT2 is highly homologous to Cluster II of KUP/HAK/KT K+transporters and is predicted to contain 11 transmembrane domains. Gh KT2 has been localized to the plasma membrane, and its transcripts were detected in roots, stems, leaves and shoot apices of cotton seedlings.Consistently, b-glucuronidase(GUS) expression driven by the Gh KT2 promoter could be detected in roots, mesophyll cells, and leaf veins in transgenic Arabidopsis. In addition,the expression of Gh KT2 was induced by low K+stress in cotton roots and p Gh KT2::GUS-transgenic Arabidopsis seedlings. The Gh KT2-overexpression Arabidopsis lines plants were larger and showed greater K+accumulation than the wild type(WT) regardless of K+concentration supplied. The net K+influx rate, measured by the noninvasive micro-test technique, in root meristem zone of Gh KT2-transgenic Arabidopsis lines was significantly greater than that of WT. Taken together, this evidence indicates that Gh KT2 may participate in K+acquisition from low or high external K+, as well as K+transport and distribution in plants.Yiru WANG Juan XU Mingcai ZHANG Xiaoli TIAN Zhaohu LI 2018Frontiers of Agricultural Science and Engineering2018,5,2:2

11Increase in root density induced by coronatine improves maize drought resistance in North China显示文摘Drought stress caused by insufficient irrigation or precipitation impairs agricultural production worldwide.In this study,a two-year field experiment was conducted to investigate the effect of coronatine(COR),a functional analog of jasmonic acid(JA),on maize drought resistance.The experiment included two water treatments(rainfed and irrigation),four COR concentrations(mock,0μmol L^(-1);A1,0.1μmol L^(-1);A2,1μmol L^(-1);A3,10μmol L^(-1))and two maize genotypes(Fumin 985(FM985),a drought-resistant cultivar and Xianyu 335(XY335),a drought-sensitive cultivar).Spraying 1μmol L^(-1)COR at seedling stage increased surface root density and size,including root dry matter by 12.6%,projected root area by 19.0%,average root density by 51.9%,and thus root bleeding sap by 28.2%under drought conditions.COR application also increased leaf area and SPAD values,a result attributed to improvement of the root system and increases in abscisic acid(ABA),JA,and salicylic acid(SA)contents.The improvement of leaves and roots laid the foundation for increasing plant height and dry matter accumulation.COR application reduced anthesis and silking interval,increasing kernel number per ear.COR treatment at 1μmol L^(-1)increased the yield of XY335 and FM985 by 7.9%and 11.0%,respectively.Correlation and path analysis showed that grain yields were correlated with root dry weight and projected root area,increasing maize drought resistance mainly via leaf area index and dry matter accumulation.Overall,COR increased maize drought resistance mainly by increasing root dry weight and root area,with 1μmol L-^(-1)COR as an optimal concentration.Yuling Guo Guanmin Huang Qing Guo Chuanxi Peng Yingru Liu Mingcai Zhang Zhaohu Li Yuyi Zhou Liusheng Duan 2023The Crop Journal2023,11,1:1
12Exogenous application of glycine betaine improved water use efficiency in winter wheat(Triticum aestivum L.) via modulating photosynthetic efficiency and antioxidative capacity under conventional and limited irrigation conditions显示文摘Improving water use efficiency(WUE)is an important subject in agricultural irrigation for alleviating the scarcity of water resources in semiarid regions of the North China Plain.Moreover,glycine betaine(GB)is one of the most effective compatible solutes synthesized naturally in plants for enhancing stress tolerance under abiotic stress,but little information is available on the involvement of GB in regulating crop WUE under field conditions.This study was conducted to explore the role of exogenously applied GB in improving WUE and plant physiological and biochemical responses inwinterwheat subjected to conventional or limited irrigation during the 2015–2016 and 2016–2017 growing seasons.Exogenous application of GB significantly enhanced antioxidant enzyme activities and reduced the accumulation ofmalondialdehyde and hydrogen peroxide under limited irrigation conditions.Furthermore,GB-treated plantsmaintained higher leaf relative water content andmembrane stability,which led to higher chlorophyll content and gas exchange attributes for better intrinsic and instantaneouswater use efficiencies compared to control plants under limited irrigation conditions.GB-treated plants had higher indole-acetic acid and zeatin riboside levels but lower ABA levels compared to control plants under conventional and limited irrigation conditions.Additionally,GB enhanced the grain filling rate and duration,grain number per spike,and final grainweight,which resulted in higher grain yield compared to the control.Interestingly,GB significantly improved the integrative and photosynthetic WUE under conventional and limited irrigation conditions,although GB treatment did not markedly affect total water consumption.These results suggest the involvement of GB in improving WUEs in winter wheat by modulating hormonal balance,membrane stability,photosynthetic performance and antioxidant systems to maintain higher grain yield under conventional and limited irrigation conditions.Nazir Ahmed Yushi Zhang Ke Li Yuyi Zhou Mingcai Zhang Zhaohu Li 2019The Crop Journal2019,7,5:1

15Brassinosteroids modulate nitrogen physiological response and promote nitrogen uptake in maize(Zea mays L.)显示文摘Brassinosteroids(BRs)are steroid hormones that function in plant growth and development and response to environmental stresses and nutrient supplies.However,few studies have investigated the effect of BRs in modulating the physiological response to nitrogen(N)supply in maize.In the present study,BR signalingdeficient mutant zmbri1-RNAi lines and exogenous application of 2,4-epibrassinolide(e BL)were used to study the role of BRs in the regulation of physiological response in maize seedlings supplied with N.Exogenous application of e BL increased primary root length and plant biomass,but zmbri1 plants showed shorter primary roots and less plant biomass than wild-type plants under low N(LN)and normal N(NN)conditions.LN induced the expression of the BR signaling-associated genes Zm DWF4,Zm CPD,Zm DET2,and Zm BZR1 and the production of longer primary roots than NN.Knockdown of Zm BRI1 weakened the biological effects of LN-induced primary root elongation.e BL treatment increased N accumulation in shoots and roots of maize seedlings exposed to LN or NN treatment.Correspondingly,zmbri1 plants showed lower N accumulation in shoots and roots than wild-type plants.Along with reduced N accumulation,zmbri1 plants showed lower NO3-fluxes and^(15)NO_(3)^(-)uptake.The expression of nitrate transporter(NRT)genes(Zm NPF6.4,Zm NPF6.6,Zm NRT2.1,Zm NRT2.2)was lower in zmbri1 than in wild-type roots,but e BL treatments up-regulated the transcript expression of NRT genes.Thus,BRs modulated N physiological response and regulated the transcript expression of NRT genes to promote N uptake in maize.Jiapeng Xing Yubin Wang Qingqing Yao Yushi Zhang Mingcai Zhang Zhaohu Li 2022The Crop Journal2022,10,1:1

17Zircon classification from cathodoluminescence images using deep learning显示文摘Zircon is a widely-used heavy mineral in geochronological and geochemical research because it can extract important information to understand the history and genesis of rocks. Zircon has various types,and an accurate examination of zircon type is a prerequisite procedure before further analysis.Cathodoluminescence(CL) imaging is one of the most reliable ways to classify zircons. However, current CL image examination is conducted by manual work, which is time-consuming, bias-prone, and requires expertise. An automated and bias-free method for zircon classification is absent but necessary. To this end, deep convolutional neural networks(DCNNs) and transfer learning are applied in this study to classify the common types of zircons, i.e., igneous, metamorphic, and hydrothermal zircons. An atlas with over 4000 CL images of these three types of zircons is created, and three DCNNs are trained using these images. The results of this study indicate that the DCNNs can distinguish hydrothermal zircons from other zircons, as indicated by the highest accuracy of 100%. Although similar textures in igneous and metamorphic zircons pose great challenges for zircon classification, the DCNNs successfully classify 95% igneous and 92% metamorphic zircons. This study demonstrates the high accuracy of DCNNs in zircon classification and presents the great potentiality of deep learning techniques in numerous geoscientific disciplines.Dongyu Zheng Sixuan Wu Chao Ma Lu Xiang Li Hou Anqing Chen Mingcai Hou 2022Geoscience Frontiers2022,13,6:0
18Analysis of differential expression of genes induced by ethephon in elongating internodes of maize plants显示文摘Plant growth regulators(PGRs) are commonly used in cereal cropping systems to restrict plant height and control lodging. Ethephon has been reported to shorten internodes and increase grain yield of maize. To analyze the transcriptomic profiles of maize internode elongation following ethephon treatment, differentially expressed genes were compared between the treatment and contro samples of inbred line Zong 31 using the Affymetrix Maize Genome Array. According to the microarray data 326 probe sets showed significant change in expression Further research revealed that the most remarkable effects of ethephon on maize internodes elongation occurred during a 48 h period, when 89 differentially expressed genes were detected. There were dramatic change in transcript levels at 24 h and six Auxin transport genes and four gibberellin biosynthesis pathway genes were differentially expressed in Zong 31 in response to ethephon treatment. In summary, we showed that gaseous ethylene release is involved in internode meristem cell elongation through the regulation of plant hormone signaling in maize. This work provides a platform for studies in which candidate genes will be functionally tested for involvement in internode elongation.Xiaoyi WEI Weiqiang ZHANG Qian ZHANG Pei SUN Zhaohu LI Mingcai ZHANG Jianmin LI Liusheng DUAN 2016Frontiers of Agricultural Science and Engineering2016,3,3:0
19Coronatine promotes maize water uptake by directly binding to the aquaporin ZmPIP2;5 and enhancing its activity显示文摘Water uptake is crucial for crop growth and development and drought stress tolerance. The water channel aquaporins(AQP) play important roles in plant water uptake. Here, we discovered that a jasmonic acid analog, coronatine(COR), enhanced maize(Zea mays) root water uptake capacity under artificial water deficiency conditions. COR treatment induced the expression of the AQP gene Plasma membrane intrinsic protein 2;5(ZmPIP2;5).In vivo and in vitro experiments indicated that COR also directly acts on ZmPIP2;5 to improve water uptake in maize and Xenopus oocytes. The leaf water potential and hydraulic conductivity of roots growing under hyperosmotic conditions were higher in ZmPIP2;5-overexpression lines and lower in the zmpip2;5 knockout mutant, compared to wild-type plants. Based on a comparison between ZmPIP2;5 and other PIP2s, we predicted that COR may bind to the functional site in loop E of ZmPIP2;5. We confirmed this prediction by surface plasmon resonance technology and a microscale thermophoresis assay, and showed that deleting the binding motif greatly reduced COR binding. We identified the N241 residue as the COR-specific binding site, which may activate the channel of the AQP tetramer and increase water transport activity,which may facilitate water uptake under hyperosmotic stress.Rui He Huiqing Su Xing Wang Zhijie Ren Kun Zhang Tianyu Feng Mingcai Zhang Zhaohu Li Legong Li Junhong Zhuang Zhizhong Gong Yuyi Zhou Liusheng Duan 2023Journal of Integrative Plant Biology2023,65,3:0
20Exploring best‑matched embedding model and classifier for charging‑pile fault diagnosis显示文摘The continuous increase of electric vehicles is being facilitating the large-scale distributed charging-pile deployment.It is crucial to guarantee normal operation of charging piles,resulting in the importance of diagnosing charging-pile faults.The existing fault-diagnosis approaches were based on physical fault data like mechanical log data and sensor data streams.However,there are other types of fault data,which cannot be used for diagnosis by these existing approaches.This paper aims to fill this gap and consider 8 types of fault data for diagnosing,at least including physical installation error fault,charging-pile mechanical fault,charging-pile program fault,user personal fault,signal fault(offline),pile compatibility fault,charging platform fault,and other faults.We aim to find out how to combine existing feature-extraction and machine learning techniques to make the better diagnosis by conducting experiments on realistic dataset.4 word embedding models are investigated for feature extraction of fault data,including N-gram,GloVe,Word2vec,and BERT.Moreover,we classify the word embedding results using 10 machine learning classifiers,including Random Forest(RF),Support Vector Machine,K-Nearest Neighbor,Multilayer Perceptron,Recurrent Neural Network,AdaBoost,Gradient Boosted Decision Tree,Decision Tree,Extra Tree,and VOTE.Compared with original fault record dataset,we utilize paraphrasing-based data augmentation method to improve the classification accuracy up to 10.40%.Our extensive experiment results reveal that RF classifier combining the GloVe embedding model achieves the best accuracy with acceptable training time.In addition,we discuss the interpretability of RF and GloVe.Wen Wang Jianhua Wang Xiaofeng Peng Ye Yang Chun Xiao Shuai Yang Mingcai Wang Lingfei Wang Lin Li Xiaolin Chang 2023Cybersecurity2023,6,3:0
